[Changes in the arterial pressure after ligation of the hypogastric artery].
The physiology of the pelvic territory after the ligation of the hypogastric arteries may be resumed in the following phenomena: the absence of bleeding, absence of ischemia and changes in pelvic vascular pattern. The hemostatic effect is noticed immediately after ligation, when the bleeding is considerably diminished, permitting to finish the surgical act. The blood pressure has been measured before ligation, immediately and it increases after five minutes due to the changes in local characteristic impedance. The impedance profile is in concordance with geometrical modification of the microvascular network made to prevent the ischemia. The increase in blood pressure five minutes after ligation is the result of the anastomosis between the ischiatic artery and other branches of the hypogastric artery, remaking the capillary bed in the pelvic territory.
